CLOSURE.

SPECIFICATION forming part of Letters Patent No. 568,486, datedSeptember 29, 1896. Application filed September 27, 1895. Serial No.563,843. (No model.)

T ctZZ whom it may concern:

Be it known that we, ALBERT S. LAMBERT and EDMUND HOFFMAN, citizens ofthe United States, residing at Bridgeton, in the county of Cumberland,in the State of New Jersey, have invented a certain new and usefulImprovement in Closures, of which the following specification is a trueand exact description,reference being had to the accompanying drawings,which form a part thereof.

Our invention relates to the construction of closures or stoppers usedfor closing bottles, cans, or other receptacles, and has for its objectto provide a closure or stopper of cheap simple construction, and whichshall combine the elastic principle of the ordinary corkstopper with apositively-locking union between the closure of the bottle or otherreceptacle to which it is applied.

The nature of our improvements will be best understood as described inconnection with the drawings, in which they are illustrated, and inwhich 7 Figure 1 is a central longitudinal section through the neck of abottle and our stopper applied thereto. Fig. 2 is a plan view of thestopper; Fig. 3, a side elevation thereof, showing in dotted lines thebottle-neck and the cork, which forms a part of the stopper. Fig. 4. isa side elevation of the metallic part of the stopper, taken at rightangles to the View shown at Fig. 3. Fig. 5 is a plan view of the blankfrom which the metallic part of the stopper is formed, and Fig. 6 is aperspective sectional view of a bottle-neck adapted for use with ourimproved stopper.

A indicates the neck of the bottle, which is formed with two channels A,situated opposite to each other and extending downward tocircumferentially-extending channels A the upper part of which, A ispreferably made with a downward slant, as indicated.

B is the cork, which may be of any convenient material, such as cork,rubber, or anything else having the same capacity to be compressed andclose the mouth of the bottle.

C is the metallic head or cap of the stopper or closure,the central partC of which covers the top of the cork B and is provided with a circulardownwardly extending flange C which embraces the upper part of the cork.The curved edge of the flange C is preferably corrugated, as shown, inorder to give a'good holding-surface for the fingers. From the loweredge of the flange C extend arms C C the ends of which should bepointed,as shown and bent inward, as indicated at 0 so as to penetrate thesubstance of the cork.

C C are also downwardly-extending arms from the flange of the cap, and CC are outwardly-bent portions of these arms, preferably formed bybending the metal into a fold, as indicated in Fig. 3, the extreme endsof the arms C being preferably pointed and bent inward, so as to engagethe substance of the cork, as is shown at C.

In inserting the closure into the bottle-neck the projecting lugs C arebrought to register with the grooves A, and the closure is then thrustdown into the bottle-neck until the lugs C come opposite to thecircumferential grooves A and by giving the upper side A of the saidgrooves a downward slant the turning of the stopper can be made to drawthe cork still farther downward. .Of course the cork or stopper isremoved by turning it until the lugs C can register with the grooves Aand then drawing it directly out.

The form of the engaging-grooves A and A may be considerably varied. Wehave shown the special form illustrated in the drawings as a desirableone; but our present invention is not concerned with the conformation ofthe bottle-neck, and any form which will provide a groove wherein thelugs C can engage themselves may be used in connection with our closure.

WVe prefer to construct the closure with the metal cap provided withfour downwardlyextending arms; but in some cases the arms C may beomitted, the arms C providing a .sufficient union between the cork andcapiece. p Having now described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. A closure having in combination a cork B and a metal cap C providedwith depending arms C the ends 0 of which are bent in arms C the ends ofwhich are folded out to and inserted in the cork, and with dependingform lugs O and then in to form anchors C 10 %rms O theJ ends of whichare folded out to ALBERT S LAMBERT O1Il1 In "S 5 2.
